Answer:3 and 7.

Step-by-step explanation:

Answer 2

Answer:

$x + \frac{1}{x } = \sqrt{5}$

$(x + \frac{1}{x} ) ^{2} = ( \sqrt{5) ^{2} } \\ {x}^{2 } + \frac{1}{ {x}^{2} } + 2 = 5(x+x1)2=(5)2x2+x21+2=5(x+x1)2=(5)2x2+x21+2=5</p><p></p><p>$

${x}^{2} + \frac{1}{ {x}^{2} } = 5 - 2 = 3$

similarly

${x}^{4} + \frac{1}{ {x}^{4} } = {3}^{2} - 2 = 7$
